Sandpaper Cutting Jig

First apologies. I wanted to respond to a forum post in jigs and fixtures about a sand paper cutter but this is easier than adding photos to the forum topic. I found this design in a woodworking magazine, probably Shopnotes. I like it because I can cut a sheet of paper into sixths quickly. The key is that there are 2 fences. The upper fence lets the user cut the sheet into thirds along the length. The lower sheet then let’s the user cut the sandpaper thirds in half. There are thin cardboard strips at the top and bottom that allow the paper to easily slide below the hacksaw blade. The sixths are a perfect size for me. They fit the corked sanding blocks I use and they are the right size to be folded for wood turning.Cheers
